CALGARY, ALBERTA--(Marketwire - July 23, 2008) - WestJet (TSX:WJA) today commented on a report of alleged fraudulent activity involving customer credit card information potentially emanating from self-serve check-in kiosks at Toronto's Pearson International Airport. WestJet announced that it will disable its credit card check-in functionality at all airport kiosks across Canada today.

WestJet has been made aware that Visa is investigating reports of a potential security breach involving credit card information at Pearson International, and has isolated the potential source as self-serve check-in kiosks. These kiosks allow airline guests from numerous air carriers using a credit card or booking reservation number to check in and print boarding passes.

While the credit card functionality is disabled, the kiosks will still accept guests' flight confirmation numbers or passports via the passport scanner. WestJet encourages guests to check in using any of the following methods:

- Web check-in

- Mobile check-in

- With a Customer Service Agent at the counter

- Using the kiosks with the flight confirmation number

- Using the kiosks with a passport

WestJet Customer Service Agents and Guest Service Ambassadors will be on hand at airports across the country to make guests aware of the situation and assist them to check in.
